Bills [20] presented a linear cumulative damage model of viscoelastic materials which can be generally used as a basic damage model to assess the experimental results on solid fuel structure.
The software has its own interpretation of the characteristic properties of the polymeric materials and that of adhesive joints.

However, with the development of modern science and technology, social, economic, cultural, and other fields have been caught up in the tide of modernization.
It also needs to mine with a local personality and history element symbols, and to make full use of the existing general layout and skin texture of the road area, lastly to apply the modern science and technology build with regional cultural features road landscape.

The outputs of the ANN model include the ultimate tensile strength (UTS) of the test material.
Thermomechanical treatment is known to improve the mechanical properties of metallic materials.
Finally, an overview of the application of neural networks to study material science problems has been developed by Bhadeshia et al [22, 23].
In addition, it is expected that an increase in the yield strength YS (having a sensitivity factor of 2.30) involves an increase of tensile strength as they measure the resistance of test material (Fig. 7).

Experimental material.
Therefore, in order to prove that 0.382 is the optimum value of SWC (fine)/ SWC (coarse) ratio in real materials, more accurate facilities, more powerful analytical software and more meticulous experiments are required.

Tribological and oxidation properties study of a kind of sodium sulfonate-modified nano carbonate sodium He Zhongyi1,2 a,Xiong Liping1b,Xu Huan1,Li Tao2,Qiu Jianwei2,Fu Xisheng2 1)School of Basic Science, East China Jiaotong University, Nanchang, PR China 2)PetroChina Lanzhou Lubricating Oil R & D Institute, Lanzhou, PR China aemail:zhongyihe@yahoo.com.cn; bemail:zhyhe@ecjtu.jx.cn Key words: alkali metal sulfonate; nano carbonate sodium; tribological property; antioxidant Abstract: The tribological properties of a high base value sodium sulfonate-modified nano carbonate sodium as lubricating oil additive were introduced in this paper, and its antioxidant collaboration property with ashless antioxidant was evaluation by using pressure differential scanning calorimetry(PDSC).
To study tribological property of sodium sulfonate which containing nano carbonate sodium applied as extreme pressure additive, and it’s antioxidant synergistic effect with antioxidant T531, alkyl benzene sulfonic acid was used as raw material to obtain high base value sodium sulfonate, and it’s tribological property was evaluated by using a four-ball machine in hydrogenation oil, its antioxidant property with T531(N-phenyl-α-naphthylamine) was also discussed in this paper.
